picked up a flintlock pistol at a pawn shop. dont know nothing about it. i know percushion BP but this is new to me. my research tells me i need a flint and possibly a frizzen as this one seems scored up pretty good. idk it may be normal wear.ive dissassembled it . it was heavily rusted and now is soaking in aerokroil. how do i know what kind of frizzen and flint i need ? the lock seems strong and operates as it should i think. the wood seems heavily soiled with not much finish left. dont know the caliber either. was cool looking.
